RaySenseLeakDetection

RaySense管道保护系统

 

A single pipeline security system protects up to 50km per APU against Third-Party Interference (TPI), Leaks, Illegal tapping attempts and unauthorised excavation.

 

  • All-In-One – Same unit and cable protect against leaks, TPI and excavation
  • The world’s first locating, ultrasonic distributed vibration sensor (DVS)
  • Up to 50km/31miles per processing – no limit in network.
  • Locate a TPI, tapping or leaking event to ±10M/±30ft resolution over the entire length.
  • Signature based detection – Wide range frequency detection, 3Hz to 500 kHz
  • 在现场不需要电子或电源。
  • IP based remote control and monitoring with 3rd party integration.

With the long fiber optic monitoring capabilities the RaySense provides 100% perimeter coverage for long range applications with no gaps between sensors, the cable is the sensor.

 

The pipeline leak detection capability is based on acoustics which allows the cable to detect without any physical movement of the cable, it can be buried in any type of ground or soil and detect even a 0.5mm hold in a high pressured pipe.

 

Distributed Vibration Sensor (DVS) Pipeline Protection System is effective in the prevention of oil spills and/or gas explosions due to its unique ability to detect, locate and classify vibrations caused by physical activity (such as third party interference – TPI), while simultaneously monitoring for early-stage leaks, along the entire length of the pipeline in real time.  It is also capable of early detection and location of dynamic geological hazards, such as landslides, or excavating activity (by equipment or hand) anywhere within the vicinity of a pipeline, and in many cases prior to the excavating operation within the right-of-way.

 

The RaySense system can be employed for real-time precise detection and location of dangerous events to pipelines.  The core RaySense technology acts as a continuous microphone designed to “monitor” over a quasi-DC to 500 kHz bandwidth, to very distinctive frequencies generated by TPI and leak events, while discriminating between normal and ambient conditions.
Furthermore, with additional channels, the RaySense system provides reliable perimeter security for processing plants, distribution or intermediate stations and storage sites.

Utilizing fiber-optic cable, the system is the most economically competitive technology currently available for long distances.  Requiring only a single alarm processing unit (APU) to cover up to 50km/31 Miles of pipeline, combined with a rugged fiber-optic sensing cable, results in the most cost-effective solution for large perimeters.
In some application the RaySense system can utilize the pre-exsiting communication cable for detection.
